The d-metal alloy Ni1-xVx undergoes a quantum phase transition from a ferromagnetic ground state to a paramagnetic ground state as the vanadium concentration x is increased. We present magnetization, ac-susceptibility and muon-spin relaxation data at several vanadium concentrations near the critical concentration xc ~ 11.6 % at which the onset of ferromagnetic order is suppressed to zero temperature. Below xc, the muon data reveal a broad magnetic field distribution indicative of a long-range… Expand

Properties and Collapse of the Ferromagnetism in UCo1−xRuxAl Studied in Single Crystals
We have investigated the ferromagnetic (FM) phase which suddenly develops in UCo1−xRuxAl and is isolated by paramagnetic regions on both sides from the parent UCoAl and URuAl. For that purpose weExpand


Probing the magnetic phases in the Ni-V alloy close to the disordered ferromagnetic quantum critical point with μSR
Zero (ZF) and longitudinal field (LF) muon spin relaxation data of the d-metal alloy Ni1-xVx are presented at several vanadium concentrations x below and above the critical xc ≈ 11 % where long-rangeExpand
Kondo-cluster-glass state near a ferromagnetic quantum phase transition.
Despite pronounced non-Fermi-liquid effects in both specific heat and thermal expansion, the Grüneisen ratio does not diverge as T --> 0, providing evidence for the absence of a quantum critical point. Expand
