Magnetic spin resonance inCeB6

Abstract: Line shape of magnetic spin resonance at 60 GHz specific to the phase II ͑so-called antiferroquadrupole phase͒ of CeB 6 was studied. The applied procedure of data analysis has allowed obtaining g factor of the oscillating magnetic moments, line width, and oscillating magnetization. It is found that the approaching to the transition temperature T I-II from phase II to the paramagnetic phase I results in strong broadening of the resonance ͑the line width increases three times in the range 1.8 K Յ T Յ 3.8 K͒ wher… Show more

“…Furthermore, the ferromagnetic correlations enhance the susceptibility (in agreement with experiment where χ 0 displays a kink 43,50 ) and hence reduce the line width of the resonance, which then becomes accessible to observation.…”

“…The AFQ phase at zero magnetic field develops below T Q = 3.2 K. Further temperature decrease transfers this compound into AFM phase below T N = 2.4 K. Magnetic field application stabilizes the AFQ phase causing an increase of T Q as well as a suppression of AFM order below T N . The experimental observation of ESR in CeB 6 [1][2][3] induced a novel theoretical approach describing ESR in the AFQ phase [5,6]. It is based on the consideration of Γ 8 state of Ce 3+ ions forming two orbitally ordered sublattices.…”

“…Electron spin resonance (ESR) in heavy fermion compound CeB 6 [1][2][3] is a puzzling phenomenon forming new aspects in the investigation of the exotic low temperature state of this system. Strong exchange interaction of local moments with conduction electrons prevents the observation of the resonance behavior of Ce 3+ ions in metals and only few systems exhibiting ESR have been reported so far ( [4] and references therein).…”

“…This paper reports detailed ESR investigations of CeRuPO in order to document the properties of the rarely observed Ce 3+ spin resonance (we are aware of only two others, namely CeP [9] and CeB 6 [10]), and to show the effect of ferromagnetic correlations and magnetic order on the Kondo ion spin resonance.…”
