**Correlations**in Transition Metals . ... the concepts involved I shall discuss the question of whether**correlation**is a strong or a weak effect .Page 88

The

The

**correlation**effect , by reducing the Coulomb energy of unlike spins , usually acts against this ferromagnetic tendency . This can be conveniently ...Page 95

Thus the polarity of the

Thus the polarity of the

**correlated**state is reduced by 22 ~ 0 ( d ) of that of the H - F state , and there thus remain a fair number of 3d8 atoms in the ...### What people are saying - Write a review
