New polarization effect and collective excitation in S=1/2 quasi 1D antiferromagnetic quantum spin chain
S. V. Demishev, A. V. Semeno, H. Ohta +4
Anomalous polarization characteristics of magnetic resonance in CuGeO3 doped with 2% of Co impurity are reported. For the Faraday geometry this mode is damped for the microwave fie…
ESR Probing of Quantum Critical Phenomena in Doped S=1/2 AF Quantum Spin Chain
S. V. Demishev, A. V. Semeno, N. E. Sluchanko +4
The results of high frequency (60-315 GHz) studies of the ESR in CuGeO3 single crystals containing 0.9% of the Mn impurity are reported. The quantitative ESR line shape analysis sh…
High frequency study of the orbital ordering resonance in the strongly correlated heavy fermion metal CeB6
S. V. Demishev, A. V. Semeno, H. Ohta +4
We report results of the study of the recently discovered magnetic resonance in the orbitally ordered phase of CeB6 (the orbital ordering resonance) in a wide frequency range 44-36…
Quantum critical behavior induced by Mn impurity in CuGeO3
A. V. Semeno, N. E. Sluchanko, N. A. Samarin +4
Results of high frequency (60-315 GHz) studies of ESR in CuGeO3 single crystals containing 0.9% of Mn impurity are reported. Quantitative EPR line shape analysis allowed concluding…
Magnetic resonance in cerium hexaboride caused by quadrupolar ordering
S. V. Demishev, A. V. Semeno, A. V. Bogach +3
Experimental evidence of the magnetic resonance in the antiferro-quadrupole phase of CeB6 is reported. We have shown that below orbital ordering temperature a new magnetic contribu…
Antiferro-quadrupole resonance in CeB6
S. V. Demishev, A. V. Semeno, A. V. Bogach +3
We report experimental observation of a new type of magnetic resonance caused by orbital ordering in a strongly correlated electronic system. Cavity measurements performed on CeB6…
