so sorry for bothering you , you have already given me more than enough help . saying'' working with para is better than ferro '' is a bit hard,i imagine . as you yourself said , not all materials would be expected to behave similarly . thank you

i seriously can not thank you enough for adding this little bit . i have a question ,does this mean that the magnetocaloric effect is stronger in paramagnetic materials ?

thank you soo much for your help , it is immensely, immensely! appreciated .

thank you so much . may i ask if you have a book/website that i can read or use as a reference ?

thank you very much for going through the trouble . so if i understand correctly : when an external magnetic field is applied to a magnetic material an energy shift happens , electrons with spin moment parallel to the applied field will have a lower energy , those with a spin moment opposed to...

i am trying to understand the magnetocaloric effect from another point of view (besides thermodynamics ) , i know that under the influence of an external field , a zeeman splitting happens , and the electrons will have different levels of energy , those with + 1/2 spin will have a higher energy...

sorry for the late reply , thank you so much for answering , it was strangely hard to find anything about it . the ppt does explain clearly why carbon prefers octa voids over tetra voids , it doesn t specify which octa void though , so i will just take it as there is no difference between the...

in steel made with ferrite ( fe with bcc ) , we have tetrahedral and octahedral sites that the carbon can occupy , we know that carbon likes to occupy octahedral sites , but there are two kinds of them . 1 : on face centers , and 2 : on edge centers . does carbon prefer one of them ? or does...

Thank you so much , I reread your replie so many times and you explained it so clearly , thank you .

i know this might seem as a very simple question , but i am confused : in order to calculate the total number of vacancies we need the total number of atomic sites N , and since N depends on the density of the material , then N refers to the number of atoms , right ? what confuses me is the word...

this is the best that i could do the probability that the dipole between x and dx is dp(x) = (1 / Z ) e^(μ(x)B cos θ) dx = dx because we assume that B is parallel to z so μ(x) . B = 0 dp(y) = (1 / Z ) e^(μ(y)B cos θ) dy = dy dp(z) = (1 / Z )e^(μ(z)B cos θ) dz d^3 p( x,y,z)= (1 / Z...

1. the problem goes like this : The energy of interaction of a classical magnetic dipole with the magnetic field B is given by E = −μ·B. The sum over microstates becomes an integral over all directions of μ. The direction of μ in three dimensions is given by the angles θ and φ of a spherical...

i think i finally understood what is going on : you see i have always assumed that they were talking about the primitive vectors , for example to calculate the reciprocal vectors in the case of body centered we had to look for the primitive lattice ( which is a simple cube ) , but doing that...

after a lot of searching , i noticed something , they do not actually mention the modulus of the vectors themselves but the lattice constant , i don t exactly understand what the difference is . lattice constant is defined as the physical dimension of unit cells in a crystal lattice. so how is...

a refers to the parameter of the elementary lattice , as a, b, c , of the simple cubic lattice . a* is the parameter of the reciprocal lattice , as in a* , b* , c* . a* , b* , c* are deduced from the parameters of the primitive lattice, a1 , a2 and a3 . in the second pic a* is b1 , b*is b2...
