Raw data associated with the publication "Gadolinium Oxyorthogermanate Gd2GeO5: an Efficient Solid Refrigerant Material for Magnetic Cryocoolers".
Steps to reproduce
(1) Magnetic susceptibility data was collected using the liquid-helium free PPMS (PPMS®DynaCool™, Quantum Design) under a dc field of B = 10 mT in the 2–300 K temperature range. The magnetization isotherms are collected at a temperature range of 2–12 K with a 1-K step after cooling in zero fields at each temperature interval, the highest field values are set to be B = 9 T. (2) Heat capacity data was collected using the commercial physical property measurement system (PPMS-9, Quantum Design) by thermal-relaxation method with Apiezon N-grease, at T = 1.9 – 40 K, the external fields are set to be 0, 2, and 8.9 T. (3) Powder X-ray diffraction data was collected at room temperature on a Huber diffraction and positioning equipment with Cu-Kα radiation. The GSAS package of EXPGUI interface was used for the Rietveld analysis.
