Static and dynamic spin-properties in oxides - how to make data public?

In recent years the collection and evaluation of private data has come to the public attention, but virtually nobody is aware of the tremendous amount of data which is being collected and created in surveys, statistics and research projects at science facilities and universities. Often those projects are publically funded and it takes years until the results are published. Even then, in most cases, only a small portion of the whole data is used and therefore available. The publication and provision of the entire raw data would make an important contribution to the transparency of funding usage as well as to the availability of data created with tax money. The aim of our proposal is to make our contribution to this undertaking and to develop a role-model for how to make scientific raw data public within a research project. It shall be feasible in the daily routine, protect the intellectual property and stimulate cooperation across the scientific community. Over a period of two years a project shall be conducted which is based in experimental solid-state physics. At the University Linz, as well as at international large-scale facilities like the European Syn- chrotron (ESRF) in Grenoble and the Stanford Synchrotron Radiation Laboratory (SSRL), measure- ment data will be collected and published in peer-reviewed journals as in a regular research project. Typically, there is no possibility for the readers of such publications to gain access to the raw-data and to compare them with own results. In this project, however, a data-repository shall be created in which the raw data will be transferred contemporarily after measurement. ckan (http://ckan.org/) is planned as software for this repository, as it is available at no charge and open-source. This guarantees the security of the data and that the repository is fully customizable. The Austrian government also intends to publish its data via ckan. The server-infrastructure will be provided by the University Linz and the repository will be registered in the Registry of Research Data Repositories (www.re3data.org) which also provides a persistent identifier (DOI). Initially, the data shall be transferred anonymously to the repository. This means that although they can be viewed and used, it is not possible to draw conclusions on preparation conditions or analyzing steps. Once the data are published in an article, all relevant information are populated into the database and they are not only freely available but also comprehensible and can be reused under the creative commons license CC-BY. At the end of the project a role model shall have been developed which is transferable to other workgroups and institutions in Austria and Europe and therefore strives to establish open data also in the natural sciences.

Static and dynamic spin-properties in functional magnetic oxides - how to make all data public? In recent years the collection and evaluation of private data has come to the public attention, but virtually nobody is aware of the tremendous amount of data which is being created in research projects at science facilities and universities. Often it takes years until the results are published. Even then, in most cases, only a small portion of the whole data is used and therefore available. The aim of this project was to publish and provide all data of the ongoing project in a data repository. The project was based in experimental solid-state physics. Over a period of 2.5 years measurement data were acquired and analyzed an published in common physics journals as usual. Commonly, the readers of such articles have no chance to see the underlying raw data and compare them to own results. However, in the course of this project the raw data were transferred contemporarily after measurement to a repository which is liked by a persistent identifier (DOI) and is freely and openly accessible. Once the data were published in an article, they were linked to the repository and the interested reader can use them in connection with the published material for better insight. Even for comprehensive studies excessive supplementary material is not required any more. Instead everyone can access and use the underlying measurement data. The scientific results are based in the field of spin-electronics, in which novel concepts are developed which shall enable to bae the processing of information not on the electric charge of the electron but on its intrinsic angular momentum, the so-called spin. In that context the spin has to be transferred and manipulated in novel materials where it usually does not exist in nature. In the curse of this project it could be shown that a static as well as a dynamic coupling between a magnetically orders spin inside a metallic ferromagnet and a magnetically disordered functional oxide exist. The coupling and its dependency on various parameters were researched in detail and evidence for the so-called spin-pumping phenomenon is found where spin could be transferred into an insulating oxide without an additional charge current. In that context also a novel insulating ferromagnetic material was investigated which can serve as alternative to the metallic ferromagnets. Both aspects may help to circumvent unwanted losses due to charge currents in spintronic devices in the future.
