摘要：

Below the Kondo temperature TK, electron spin resonance ( ESR) usually is not observable from the Kondo ion itself because the characteristic spin fluctuation energy results in a huge width of the ESR line. The heavy- fermion metal YbRh2Si2 seems to be an exceptional case in which definite ESR spectra show characteristic properties of the Kondo ion Yb3+ well below TK. We found that the spin dynamics of YbRh2Si2, as determined by its ESR relaxation, is spatially characterized by an anisotropy of the zero- temperature residual relaxation only.
