Superconducting and ferromagnetic phase diagram of UCoGe probed by thermal expansion
We report thermal expansion measurements on a single crystal of the superconducting ferromagnet UCoGe for magnetic fields applied along the main orthorhombic axes. The thermal expansion cell was mounted on a piezoelectric rotator in order to fine-tune the magnetic field angle. The superconducting and magnetic phase diagram has been determined. With our bulk technique we confirm the S shape of t...
متن کاملEnhancement of superconductivity near the ferromagnetic quantum critical point in UCoGe.
We report a high-pressure single crystal study of the superconducting ferromagnet UCoGe. Measurements of the ac susceptibility and resistivity under pressures up to 2.2 GPa show ferromagnetism is smoothly depressed and vanishes at a critical pressure p(c) = 1.4 GPa. Near the ferromagnetic critical point superconductivity is enhanced. Upper-critical field measurements under pressure show B(c2)(0...
متن کاملElectrical resistivity study of CeZn11: Magnetic field and pressure phase diagram up to 5 GPa
Thorough resistivity measurements on single crystals of CeZn 11 under pressure p and magnetic field H are presented. At ambient pressure, CeZn 11 orders antiferromagnetically at T N = 2 K. The pressure dependence of the resistivity reveals an increase of the Kondo effect. We determine the pressure evolution of the magnetic exchange interaction between conduction and localized 4f electrons. It q...
متن کاملMultiprobe experiments under high pressure: resistivity, magnetic susceptibility, heat capacity, and thermopower measurements around 5 GPa.
We have performed multiprobe experiments using a Bridgman-anvil pressure cell, adapted to trap Daphne oil as pressure medium. Resistivity, ac-magnetic susceptibility, thermopower, and ac-heat capacity of a type-I superconductor, lead, have been studied at low temperature up to 5+/-0.1 GPa. This is the first report where ac-magnetic susceptibility has been measured in this type of pressure cell ...
متن کاملSingle Phase AC Measurements Revisited
DID YOU KNOW ? Charles Proteus Steinmetz (1855-1923) was born in Breslau, Germany, the son of a railway worker. His political activity forced him to flee Germany. He came to America and was soon employed by General Electric to head up their research facility. He was referred to as “the wizard of Schenectady”, “the forger of thunderbolts”, and “the latter-day Vulcan”. Harvard University said of ...
