Singlet magnetism in heavy fermions.
We consider singlet magnetism for the uranium ions in UPt3 and URu2Si2 assuming that time-reversal symmetry is broken for the coherent state of intermediate valence. The relative weight of the two involved configurations should be different for UPt3 and URu2Si2. If in UPt3 the configuration 5f 1 on the U-ion prevails in the coherent state below the magnetic transition, the magnetic moment would...
متن کاملSinglet-ground-state Magnets Coupled with Nuclear Spins. Systems with Singlet-doublet and Singlet-triplet Ions
Magnetic properties are studied of a system having two types of electronic singlet-ground-state ions, d-ion (singlet-doublet) and t-ion (singlet-triplet), by taking account of the hyperfine coupling. It is shown that the exchange interaction between the d-ion and the t-ion electronic spins affects crucially the magnetic properties. The results are discussed in connection with the experimental r...
متن کاملSinglet excitations in pyrochlore: a study of quantum frustration.
We apply the contractor renormalization (CORE) method to the spin half Heisenberg antiferromagnet on the frustrated checkerboard and pyrochlore lattices. Their ground states are spin-gapped singlets which break lattice symmetry. Their effective Hamiltonians describe fluctuations of orthogonal singlet pairs on tetrahedral blocks, at an emergent low energy scale. We discuss low temperature thermo...
متن کاملGround state selection under pressure in the quantum pyrochlore magnet Yb2Ti2O7
A quantum spin liquid is a state of matter characterized by quantum entanglement and the absence of any broken symmetry. In condensed matter, the frustrated rare-earth pyrochlore magnets Ho2Ti2O7 and Dy2Ti2O7, so-called spin ices, exhibit a classical spin liquid state with fractionalized thermal excitations (magnetic monopoles). Evidence for a quantum spin ice, in which the magnetic monopoles b...
متن کاملEvidence for the singlet-dimer ground state in an S = 1 antiferromagnetic bond alternating chain.
Susceptibility, ESR, and magnetization measurements have been performed on single crystals of an S = 1 bond alternating chain compound: [Ni(333-tet) (mu-NO2)] (ClO4) (333-tet = N,N'-bis(3-aminopropyl)propane-1,3-diamine) and the compound doped with a small amount of Zn. We observed an anomalous angular dependence in the Zn-doped sample. These results are well explained by the model based on the...
