Longitudinal field μSR measurements in applied fields parallel and perpendicular to the c-axis of the hexagonal heavy-fermion antiferromagnet Ce(7)Ni(3) served to monitor the 4f-spin dynamics across the magnetic phase diagram in the B-T plane, which

We report on a muon spin relaxation and rotation ( μ SR) study in cubic Ca 0.995 La 0.005 B 6 . The oriented sample has practically the lattice parameters of CaB 6 – space group P m 3 m . A μ SR investigation of CeB 6 , isostructural with CaB 6 a

We report on measurements of the Knight shift and relaxation behavior of spin polarized positive muons (µ + ) implanted in monocrystalline CeRhSn. A two-component signal is seen below 100 K which appears to indicate the presence of two different typ

Monocrystalline CeCu 2 has been studied by muon-spin rotation and relaxation (μSR) spectroscopy, using transverse- and longitudinal-field techniques between 5 and 300 K for the paramagnetic state, and in zero field (ZF) for the ordered antiferromagn

We report on measurements of the Knight shift K and spin–lattice relaxation rate λ of positive muons (μ+) implanted in cubic CeAg, a compound which is known to possess ferromagnetic ( K) and ferroquadrupolar (TQ = 15–16 K) order. The zero field

The muon-spin relaxation technique has been used to investigate the transition from a nonmagnetic to a magnetic ground state in Yb(Cu1−xNix)2Si2. The effect of the chemical substitution of Cu by Ni on the magnetic properties is evidenced by an unus

S= 1 2 KCuCl 3 has a singlet ground state with a finite spin energy gap Δ=31 K to triplet excited states. The bulk magnetic susceptibility vanishes for T ⪡ Δ according to the singlet nature of the ground state. Astonishingly, recent muon spin rel

Tetragonal HoB2C2 is one of the few compounds which show antiferroquadrupolar ordering below the onset of antiferromagnetic order (T Q =4.5 K , T N =5.9 K ) . We have started the study of this system with the ultimate aim to learn more about the inte

We report on transverse-field μSR measurements in TmNi 2 B 2 C (T N =1.5 K , T c =11 K ) single crystals aimed at the study of μ + -induced modifications in the local magnetic response. The μ + Knight shift scales with the bulk magnetic susceptibi

The magnetic phase diagram of Ce7Ni3 has been investigated in the H–T plane by TF- and LF-μSR spectroscopy at 200 and 400 mK . The observed transition from the antiferromagnetic state in zero field to an unidentified intermediate state at 0.2 T is
