Influence of a magnetic field on the antiferromagnetic order in UPt3.

چکیده
A neutron diffraction experiment was performed to investigate the effect of a magnetic field on the antiferromagnetic order in the heavy fermion su-perconductor UPt 3. Our results show that a field in the basal plane of up to 3.2 Tesla, higher than H c2 (0), has no effect: it can neither select a domain nor rotate the moment. This has a direct impact on current theories for the superconducting phase diagram based on a coupling to the magnetic order.

Magnetic quantum critical point and superconductivity in UPt3 doped with Pd.
Transverse-field muon spin relaxation measurements have been carried out on the heavy-fermion superconductor UPt (3) doped with small amounts of Pd. We find that the critical Pd concentration for the emergence of the large-moment antiferromagnetic phase is approximately 0.6 at. %Pd. At the same Pd content, superconductivity is completely suppressed. The existence of a magnetic quantum critical ...

The spin degrees of freedom play an essential role in heavy-fermion superconductivity. In UPt3, not only may spin fluctuations provide the pairing mechanism, but the existence of antiferromagnetic order below T„(with a magnetic moment —0.02ptt) ' allows the possibility of multiple superconducting phases. Similarly, recent magnetic x-ray and neutron-scattering studies of URuzSi2 establish the mi...

In this paper a simple model calculation of spin wave is given for the ferromagtic layer in ultra thin ferromagnetic/antiferromagnetic bilayer. In this model the magnetic layer is assumed as an isolated layer but the effect of antiferromagnetic layer on ferromagnetic layer and unidirectional anisotropy, is given in the effective field applied on each spin. The thin layer is assumed as two-dim...
متن کاملInvestigation of effect of magnetic ordering on structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) using ab initio method
Structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) were studied for each of three magnetic configurations nonmagnetic, ferromagnetic, and antiferromagnetic by using density functional theory in generalized gradient approximations (GGA) and strong correlation correction (GGA + U). Due to magnetic transition from antiferromagnetic to nonmagnetic phase, an electr...
