Ali Hussain, Reshak, Prof. Dr. Kashyap, Manish K. msphysik09@gmail.com maalidph@yahoo.co.uk manishdft@gmail.com Ab initio calculations Half-metallic ferromagnetism Quaternary Heusler alloys Link to publisher's homepage at http://www.elsevier.com/ A new quaternary Heusler alloy FeCrMnSb is identified by employing ab initio electronic structure calculations. It is stable in Y-structure which is also verified by various conditions governed by elastic constants c ij. It is a true half-metallic (HM) ferromagnet with integer magnetic moment of 2.00 μB per formula unit. The values of minority band gap and HM gap are found to be 0.65 eV and 0.1 eV, respectively. The HM character of FeCrMnSb sustains for 6% to 9% of uniform strain and 9% to 12% of tetragonal strain. This new quaternary Heusler alloy can be proved as an ideal candidate for spin valves and magnetic tunnel junction applications (MTJs). 2014-06-25T03:46:51Z 2014-06-25T03:46:51Z 2013 Article Journal of Solid State Chemistry, vol. 208, 2013, pages 201-204 0022-4596 http://www.sciencedirect.com/science/article/pii/S0925838813012711 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35868 10.1016/j.jallcom.2013.05.111 en Elsevier B.V. |
