Fluctuation theorem for spin transport at insulating ferromagnetic junctions
نویسندگان
چکیده
General relations for nonequilibrium spin transport at a magnetic junction between normal metal and ferromagnetic insulator are derived from the quantum fluctuation theorem. They include extended Onsager conductance spin-current noise that hold states driven by an external current. These relations, valid general setup of Hall magnetoresistance, provide comprehensive viewpoint understanding unidirectional magnetoresistance in insulating junctions.

Spin-fluctuation-dominated electrical transport of Ni3Al at high pressure
We present the study of a magnetic quantum phase transition in the itinerant-electron ferromagnet Ni3Al at high pressures. Electrical resistivity measurements in a diamond anvil cell at hydrostatic pressures up to 100 kbar and temperatures as low as 50 mK indicate that the Curie temperature collapses towards absolute zero at a critical pressure pc close to 80 kbar. Over wide ranges in pressure ...

We report a strong effect of interface-induced magnetization on the transport properties of magnetic tunnel junctions consisting of ferromagnetic manganite La0.7Ca0.3MnO3 and insulating cuprate PrBa2Cu3O7. Contrary to the typically observed steady increase of the tunnel magnetoresistance with decreasing temperature, this system exhibits a sudden anomalous decrease at low temperatures. Interesti...

We investigate theoretically the Seebeck effect in materials close to a ferromagnetic quantum critical point to explain anomalous behaviour at low temperatures. It is found that the main effect of spin fluctuations is to enhance the coefficient of the leading T-linear term, and a quantum critical behaviour characterized by a spin-fluctuation temperature appears in the temperature dependence of ...
متن کاملSpin-polarized tunnelling, magnetoresistance and interfacial effects in ferromagnetic junctions
The pioneering studies of spin-polarized tunnelling by Meservey and Tedrow in the early 1970s showed that the conduction electrons in ferromagnetic (FM) metals are spin polarized and that the spin is conserved in the tunnelling process. Only recently (1995) improved material fabrication techniques have permitted realization of the JullieÁ re quantitative model, showing that tunnelling in ferrom...
