Low magnetic loss ferrite material with a yttrium and iron based garnet structure conforms to a specified chemical formula. A low magnetic loss ferrite material with an yttrium and iron based garnet structure conforms to the following chemical formula: YaTRbFecAldIneCafCugZrhViCojSikO12/ psi where TR is a rare earth or combination of rare earths and 3(a+b+c+d+e) + 2(f+g+j) + 4(h+k) + 5I = 24 / 2 psi 1 = a = 3.5; 0 = b = 1.5; 4 = c = 5; 0 = d = 1.5; 0 = e = 0.8; 0 = f = 1; 0.05 = g = 1; 0 = i = 0.8; 0 = j = 0.5; 0 = k = 0.5. Independent claims are also included for: (a) a magnetic component incorporating a magnetic core of this material; (b) a magnetic component incorporating a circulator or a hyperfrequency dephaser made from this material; (c) a method for the fabrication of this material.
