We report a determination of the antiproton magnetic moment, measured in a three-body system, independent of previous experiments. We present results from a systematic study of the hyperfine (HF) structure of antiprotonic helium where we have achieved a precision more than a factor of 10 better than our first measurement. A comparison between the experimental results and three-body quantum elec...

and those denoted ‘estimate’ were calculated by extending the SQUID measurement to the 5% and 2.5% Feridex magnetocapsules. FIG. 1. PDQ-calculated magnetic moment distribution for 3,692 individual magnetocapsules. Magnetocapsules were randomly dispersed in 12 separate agarose gel phantoms. Numerical magnetic moment values are in Table 1. PDQ’s ability to measure magnetic moment is demonstrated ...

Magnetization and resistivity measurements have been carried out on the equiatomic ternary compound NdNiSn in the temperature range 2 200K. The compound crystallizes in the orthorhombic CeNiSn-type structure with space group Pna21. Magnetic susceptibility shows a distinct feature at TN = 3 K (Néel temperature), typical of a phase transition from an antiferromagnetic to paramagnetic state. In th...

Measurements of Rayleigh light scattering and Cotton-Mouton (CM) effect are carried out at room temperature for 100 mM NaCl solutions of apoferritin/ferritin loaded with 0, 90, 100, 500, 700, and 1500 Fe atoms/molecule. Because of the spherical shape, ferritin macromolecule should not manifest magnetic anisotropy; however, in solution it shows the induced magnetic birefringence (CM effect) and ...

We give a review on a recently developed powerful method for investigation of different phenomena that can appear when neutrinos and electrons move in background matter with special focus on the spin phenomena. This paper is devoted to the problem of neutrino and electron motion in a dense matter with special focus on the spin phenomena. It has been proven in recent oscillation experiments that...

We have investigated the role of the 4f moment on the magnetoelectric (ME) effect of orthorhombic RMnO3 (R=rare earth ions). In order to clarify the role of the 4f moment, we prepared three samples: (Eu,Y)MnO3 without the 4f moment, TbMnO3 with the anisotropic 4f moment, and (Gd,Y)MnO3 with the isotropic 4f moment. The ferroelectric behaviors of these samples are different from each other in a ...

A main challenge in understanding the defect ferromagnetism in dilute magnetic oxides is the direct experimental verification of the presence of a particular kind of defect and distinguishing its magnetic contributions from other defects. The magnetic effect of hydroxyls on TiO nanoclusters has been studied by measuring the evolution of the magnetic moment as a function of moisture exposure tim...

We study the neutrino-photon processes like γγ → νν̄ in the presence of uniform external magnetic field for the case when neutrinos can couple to the electromagnetic field directly through their dipole magnetic moment and obtain the stellar energy loss. The process would be of special relevance in astrophysical situations where standard left-handed neutrinos are trapped and the right handed neut...

In this paper we present an analysis of the magnetic toroidal moment and its relation to the various structural modes in R3c-distorted perovskites with magnetic cations on either the perovskite A or B site. We evaluate the toroidal moment in the limit of localized magnetic moments and show that the full magnetic symmetry can be taken into account by considering small induced magnetic moments on...
