Aims: In the present work we explore magnetic properties especially spin glass, antiferromagnetic and paramagnetic states of diluted magnetic semiconductors (A1-xMnxA' (A = Zn, Cd and A' = S, Te, Se)). Place: Department of physics, College of natural sciences, Addis Ababa Univers...
The paper presents a framework for the construction of an elementary proof of the infinitude of twin primes. It starts from the fact that all positive integers can be divided into numbers that can lead directly to a pair of twin primes (called twin ranks) and numbers (called non-...
