The particle is placed in a magnetic field B = taBoĉ + 72B,2. • Using the explicit form of Pauli spin matrices write down the Hamil- tonian H = -0,S.B and hence find its eigen values. • Assume that at time t = 0 the particle is in the eigen state of S, with eigen value –ħ/2. ...

WebIt is clear that the magnetic susceptibility of a spin-1/2 paramagnetic substance takes the form. The fact that is known as Curie's law, because it was discovered experimentally by Pierre Curie at the end of the nineteenth century. At low temperatures, , so the magnetization becomes independent of the applied field. WebMay 15, 2013 · The behavior of the spin 1/2 system in a magnetic field is interesting experimentally since particle with spin have magnetic dipole moments.
