Direct Observation of Local Magnetic Field Generated by Micro-Magnet
Using standard nuclear magnetic resonance (NMR) technique and a well-fabricated sample, we have succeeded in directly observing local magnetic field generated by a micro-magnet Ni45Fe55 (the thickness of 400-nm) which was sputtered on an Al layer of 20-nm thickness. Improved sensitivity of our NMR technique enabled us to clearly observe Al-NMR signals, which are confirmed to come from Al nuclei...
متن کاملFe b 20 06 Experimental observation of optical rotation generated in vacuum by a magnetic field
We report the experimental observation of a light polarization rotation in vacuum in the presence of a transverse magnetic field. Assuming that data distribution is Gaussian, the average measured rotation is (3.9 ± 0.5) 10−12 rad/pass, at 5 T with 44000 passes through a 1 m long magnet, with λ = 1064 nm. The relevance of this result in terms of the existence of a light, neutral, spin-zero parti...

We report the experimental observation of a light polarization rotation in vacuum in the presence of a transverse magnetic field. Assuming that data distribution is Gaussian, the average measured rotation is (3.9 +/- 0.5) x 10(-12) rad/pass, at 5 T with 44 000 passes through a 1 m long magnet, with lambda = 1064 nm.

متن کاملRotation Generated in Vacuum by a Magnetic Field ”
In a recent letter [1] the PVLAS collaboration reported the observation of optical rotation induced in vacuum by an external magnetic field. More recently [2] the same group reported also the observation of vaccuum birefringence under similar conditions. In this comment I wish to point out that the reported results are excluded at the 95% confidence level by a previous experiment [3] carried ou...
متن کاملDirect observation of non-Gaussian distribution of local magnetic properties in ferromagnetic thin films
We report our experimental finding that magnetic properties of Co-based multilayer films are shown to exhibit their local variations far from the Gaussian ~or Lorentzian! distribution which are usually assumed. The local variations of the coercivity and the field dependence l(52]ln t/]H) were determined from measurements of the hysteresis loop and the field-dependent switching time t , respecti...
