Magnetic quantum tunnelling in Fe8 with excited nuclei
Oren Shafir, Amit Keren, Satoru Maegawa +2
We investigate the effect of dynamic nuclear spin fluctuation on quantum tunneling of the magnetization (QTM) in the molecular magnet Fe8 by increasing the nuclei temperature using…
The interaction between the magnetic and superconducting order parameters in a La1.94Sr0.06CuO4 wire
Meni Shay, Amit Keren, Gad Koren +9
We investigate the coupling between the magnetic and superconducting order parameters in an 8 m long meander line ("wire") made of a La1.94Sr0.06CuO4 film with a cross section of 0…
Electromagnetic radiation emanating from the molecular nanomagnet Fe8
Oren Shafir, Amit Keren
Photons emitted by transition between the discrete levels of single molecular magnets might obay the elementary condition for Dicke's super-radiance. We investigate this possibilit…
Experimental Estimates of Dephasing Time in Molecular Magnets
Amit Keren, Oren Shafir, Efrat Shimshoni +3
Muon spin relaxation measurements in isotropic molecular magnets (MM) with a spin value S ranging from 7/2 to 27/2 are used to determine the magnitude and origin of dephasing time…
Demonstrating Multi-bit Magnetic Memory in the Fe8 High Spin Molecule by Muon Spin Rotation
Oren Shafir, Amit Keren, Satoru Maegawa +3
We developed a method to detect the quantum nature of high spin molecules using muon spin rotation, and a three-step field cycle ending always with the same field. We use this meth…
Universal linear relations between susceptibility and Tc in cuprates
Amit Kanigel, Amit Keren, Arkady Knizhnik +1
We developed an experimental method for measuring the intrinsic susceptibility χof powder of cuprate superconductors in the zero field limit using a DC-magnetometer. The method is…
