Abstract :
As well known, MnX alloys of about an equiatomic composition such as MnAl, MnBi and MnGa exhibit unique magnetism, in particular possess very high magnetic anisotropy constant K, suitable for permanent magnets and spintoronics applications. It is known that bulk MnRh exhibits para-magnetism at around 300 K and anti-ferromagnetism at lower temperature at around 77 K. However, little study of the magnetic properties in MnRh thin films has been reported. In the present study, MnRh thin films are prepared on MgO single-crystal substrates with different orientations under similar experimental conditions. The effects of substrate orientation on the structure and the magnetic properties are investigated.
