magneto-ionic1925
1925 Appleton & Barnett in Electrician 3 Apr. 398/1 The same theory (for which we propose the name magneto-ionic theory) has also been independently put forward by Messrs. Nicholls and Schelling (‘Nature’, March 7th, 1925).
1932 E. V. Appleton in Jrnl. Inst. Electr. Engineers 71 645/2 It is highly probable that interference between the various magneto-ionic components of singly- and multiply-reflected downcoming waves is partly responsible for resultant intensity fading.
1992 S. P. Maran Astron. & Astrophysics Encycl. 7/2 In almost every case, one of the radio lobes is depolarized by passage through a magnetoionic medium.
