Chapter 23 Magnetic properties of solids

Example 23.1 Page no 268

In [5]:
#Given
u=9.3*10**-24                   #Joule/tesla
ub=5.6*10**-5                  #ev
Kb=0.025                          #ev

#Calculation
A=ub/Kb
print"Magnetic interaction is", A*10**3,"*10**-3"

Magnetic interaction is 2.24 *10**-3

Example 23.2 Page no 269

In [17]:
#Given
N=2.8*10**-13
a=27*10**23
b=0.53*10**-8

#Calculation
x=-(a*N*b)/3.0

#Result
print"Diamagnetic susceptibility is", round(x*10**-4,2),"*10**-5"

Diamagnetic susceptibility is -0.13 *10**-5
