Natural quartz single crystals (α-SiO2) have been exposed to pulsed heavy ion beams (12C, 19F, 32S) with energies of 1 MeV amu−1 in the electronic slowing down regime. The simultaneous recording of the ion fluence and emitted photons with time-res

The dielectric and ac/dc transport properties of single crystals of yttrium iron garnet (Y3Fe5O12 and Y3Fe5O12:Si), and barium hexaferrite (BaFe12O19 and BaFe12O1 9:Co,Ti) were investigated after irradiations with Xe and Pb ions in the GeV range. In

We have studied the luminescence of natural SiO2 quartz induced by irradations with heavy ions in the MeV amu−1 range. The spectra obtained with sample temperatures of ∼ 85 K have the same features and line shapes, irrespective of the fluence (φ

Amorphous latent tracks can be produced in the magnetic insulators, like yttrium iron garnet (Y3Fe5O12 or YIG), by irradiations with swift heavy ions in the electronic slowing down regime. For this, the electronic stopping power must be higher than a

Thin Kapton-H films were irradiated with swift heavy ions in the MeV amu −1 range. The ion beam-induced insulator-conductor transition was studied in situ by dc and ac measurements. Electron spin resonance (ESR) measurements on outgassed samples we

The space charge formation and relaxation in poly(imide) Kapton thin films, deep-implanted with heavy ions in the MeV amu−1 range, have been studied by on-line measurements, with the pressure wave propagation method. The measured space charge depth
