ESR study of spin dynamics in the ternary phosphide YbRh6P4

We have used electron spin resonance (ESR) to investigate the YbRh6P4 powder samples. It is shown that the exotic ESR absorption is caused here by hybridization effects between the Yb 4f-orbitals and the wave functions of the conduction electrons (CE) of the outer electronic shells. A broadening and...

Description
Summary:We have used electron spin resonance (ESR) to investigate the YbRh6P4 powder samples. It is shown that the exotic ESR absorption is caused here by hybridization effects between the Yb 4f-orbitals and the wave functions of the conduction electrons (CE) of the outer electronic shells. A broadening and disappearance of the ESR line at temperatures above 10 K can be explained by the processes of the spin-lattice relaxation of the Yb3+ ions through the first excited Stark sublevel with an activation energy Δ ≈ 82.1 K.
