Spin wave investigations of the electron (Si) doped CeRu2Al10

DOI

CeRu2Al10 belongs to the CeT2Al10 family (T: Ru, Os, Fe), which exhibits Kondo-insulator behavior and high magnetic ordering temperature (TN=27K), with an unusual competition of a strongly anisotropic magnetic exchange interactions and single ion crystal field (CEF) anisotropy. In CeRu2Al10 the magnetic moment is not along the a-axis, which is the easy axis of CEF, but along the c-axis with reduced value (0.39µB). The spin wave analysis of CeRu2Al10 reveals the presence of strong anisotropy exchange, stronger along z-direction compared to xy-plane. Our recent study of electron doping (i.e. CeRu2Al10-xSix) shows a dramatic effect on the magnetic moment and its direction. The ordered state moment of the x=0.1 is ~1µB and is along the a-axis, indicating CEF governs the moment direction and anisotropic exchange has weaken. We therefore propose here to study the spin wave in Si doped CeRu2Al1
