Longitudinal magnetic moment

The fluctuating part of the longitudinal magnetic moment was calculated as (14) ... 

Sauer et al. [185] determined the gyromagnetic ratio g(9/2)/g(7/2) and the magnetic moment of the 6.2 keV level in Ta in two ways, (1) from the Zeeman split velocity spectrum of a metal source in a longitudinal field versus a Ta... 

Assuming an axially symmetric potential, the anisotropy energy of n) will be an even function of the longitudinal component of the magnetic moment s n. The averages we need to calculate are aU products of the form = (n =i (cn ))a> where the c are arbitrary constant vectors. Introducing the polar and azimuthal angles of the spin d, tp), we can write as... 

Note that Eqs. (4.127)-(4.130) describe only the longitudinal (with respect to the easy axis) relaxation of the magnetic moment. We remark that under condition 0) L, that is, far from the ferromagnetic resonance range, the transversal components of hi = p(e) are of minor importance. 

From Eqs. (4.126) and (4.127) one finds that the longitudinal component of the magnetic moment evolves according to... 

Here we focus on the longitudinal situation and assume that the imposed fields are collinearly directed along the anisotropy axis n. Then the set of the angular variables reduces to the polar angle fi of e with respect to it. Setting cos ) (e n) = x, at Hp = const for the equilibrium distribution function of the particle magnetic moment, one gets... 

Relaxation behavior is deduced from measurements of various transient phenomena. Current interpretations of these phenomena dictate the definition of two processes by which the orientations of the nuclear magnetic moments reach the equilibrium distribution. These processes are described by characteristic times, designated Ti and T2. The first, Ti, is called the thermal or longitudinal relaxation time.
