Re: [Wien] How to simulate the spin reorientation in the magnetic study

Thanks Mr Victor for the clarification because I was wondering if I am not able to ask good questions. I am from Algeria and I am working on the antiferromagnetism in some materials and I wanted to know how to simulate magnetic phase transition with spin reorientation. Thank you for the link of

Re: [Wien] [SPAM?] optical properties

but I also understand it. But what does the figure, note that the x-axis have the energy and the y-axis also have energy. I do not know what the figure represents absorption. Do you have Facebook. Em 16/06/2016 14:27, Lenka Zajickova escreveu: > Hello Antonio, > optical properties of

Re: [Wien] [SPAM?] optical properties

Hello Antonio, optical properties of material means in general its dielectric function (having real and complex parts). Alternatively, you can describe them by material refractive index and extinction coefficient. These quantities are energy (wavelength) dependent and determine how much of the

Re: [Wien] Constrained LDA calculations to find effective U

Respected Dr. P. Blaha, Thank you for your reply. I tried to reproduce the effective U for NiO according to the procedure given in the textbook section of wien2k.at. I computed the value of U=0.09 Ry, which is much less than as mentioned in notes where U=0.438 Ry. I think some mistake may

Re: [Wien] How to simulate the spin reorientation in the magnetic study

Thanks Mr Victor for your reply I have learned from the literature that spin-orbit coupling is involved in the spin orientation . Even for a ferromagnetic or a antiferromagnetic state , the spins have different orientations. How can we determine the orientation of the spins according to the use
