The magnetic moments of the three manganese sites order with a two-dimensional canted spin arrangement. The moments of two sites point along c with z(Mn2) = z(Mn3) = 3.8(2) B /atom while the Mn(l) site has a magnetic moment of 5.4(2) B /atom located in the (101) orthorhombic...
In magnetic memories, two well-defined magnetic states can be evidenced as the two directions, and the magnetic moment of a piece of ferromagnetic metal can take along one axis in space: “1” and “0” can simply be represented by the “up” and “down” directions, respectively, of ...
In this work we report the detection of the induced magnetic moment associated with the7F2state of Eu3+ions which is involved in optical emission. We used X-ray magnetic circular dichroism (XMCD), which is the difference between the X-ray absorption spectra (XAS) for left- and right-circul...
7.1.1 Magnetic properties of materials The magnetic behavior of a material is primarily determined by the electronic structure that causes magnetic diploes. One of the basic properties of a magnetic dipole is the magnetic moment. The magnetic moment has its origin primarily in the spinning of the...
of Mn ions in the interior has the moment being equal to three magnetic moments of a single manganese ion (4.4 渭B), the moment of the tetrahedral Td cluster with the Mn tetrahedron in the interior is equal approximately to twelve magnetic moments of the single manganese ion (15.5 渭B)....
{K}\,\), a magnetic field of 0.5 T suffices to align thegvector along the field direction in the entire sample. At the same time the net magnetic moment detected by SQUID magnetometry (see Supplementary Fig.2) remains unchanged between 300 K and 400 K, such that ferromagnet-...
The magnetic properties of Mn ultra-thin films epitaxially grown on (001) bcc Fe are studied by soft X-ray magnetic circular dichroism. At room temperature, the Mn growth is two-dimensional without interdiffusion in Fe, as checked by RHEED and Auger spectroscopy. A net Mn magnetic moment is...
早期研究较多的是替代元素的离子半径变化上，由于替代离子半径的改变，使a位平均半径变ylll化，致使公差因子改变，使mn o长、键角变化，晶格效应的作用使化合物的磁性、电性、 cmr效应发生改变。Abstract : the magic moment of a hydrogen atom is calculated by using the solution of the ...
On the other hand, the hyperfine magnetic field (-296 kOe) originating from 3d magnetic moment of Mn^ is virtually the same in both systems. The values of J and H_ are discussed in relation with the spin density in 2p_σ orbitals of the oxygen ions. 展开 关键词: supertransferred ...
magnetic response. A field-dependent response is typically a signature of a spontaneous moment, heralding the onset of ferro- (θ>0), ferri-, or cantedantiferromagnetic(θ<0) behavior. For an antiferromagnet χ passes through a maximum and typically drops to 2/3χmaxin the low temperature ...
