AbstractThe temperature dependences of the layer parameters $\sigma$ n, z = <$\mu$n, z>, mn, z=<Sn, z>and qn,z=<Sn,z2> of a magnetic Ising superlattice consisting of two ferromagnetic Ising materials with spins $\mu=1/2$ and S =1 respectively, on a simple cubic structure, are examined using the effective field theory based on the use of a probability distribution technique that correctly accounts for the single site kinematic relations. According to the values of the exchange interactions, different qualitative types of phase diagrams are expected.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
